Scope

This Standard specifies the terms and definitions, principle of heat distribution
test, heat distribution test instruments, preparation before heat distribution test,
heat distribution test records, heat distribution data analysis, test report, and
anomaly analysis requirements of heat distribution test for food thermal
sterilization equipment; and gives recommendations on the number of food heat
penetration tests and validity period.
This Standard applies to the heat distribution test for thermal sterilization
equipment, such as high-pressure static type (vertical, horizontal, including
spray type, full water type), rotary type, high-pressure basketless type,
hydrostatic pressure type, atmospheric-pressure water-bath continuous type,
atmospheric-pressure tunnel continuous type, atmospheric-pressure steam
box, and water-bath sterilization tank (pool), which use steam, hot water, steam-
air-water, or steam-air mixture as heat-transfer medium.
This Standard does not apply to the heat distribution test of microwave heating
and flame heating sterilization equipment.
